“Retailers and growers say they’ve been stunted by complex regulations, high taxes and decisions by most cities to ban cannabis shops. At the same time, many residents are going to city halls and courts to fight pot businesses they see as nuisances, and police chiefs are raising concerns about crime triggered by the marijuana trade.” Also, people are just as happy buying marijuana illegally. https://www.latimes.com/politics/la-pol-ca-marijuana-year-anniversary-review-20181227-story.html
We had a couple of cannabis shops open a few miles from the house. Very sketchy. I would not have wanted them in the neighborhood. Nothing against marijuana, or selling it, but these places looked more like peep shows than any legitimate retail business.
